Sigma 10–20mm F3.5 EX DC HSM

So I'm a little disappointed with this lenses image quality. The middle of its images are great, but those corners really are important on any wide-an...

I did review that lens where I kind of talked about the build quality a little bit. I wasn't super impressed by it.

I would easily have rated this a 4 on image quality alone. Build quality is better than what I expected for a $400 lens. The thing feels like a pro-grade piece of kit. I'm extremely disappointed with its autofocus, specifically how loud and "clanky" it is. It very well could be the individual produc...

I bought this lens for a trip to Hawaii, and got all of the great shots I could ask for. In fact, I used this lens the most out of the four I brought. I also brought a 50mm, 17-200mm, and a 28-70mm. On my 7d, the shots were pretty clear with no huge issues in quality toward the outside of the photos...

I've had two Sigma lenses go bad on me now (the second after I ordered this to replace the first, or I would not have ordered it). On both lenses, the aperture petals become sticky over time. When I took the first one in for repair, Sigma told the shop that they no longer had parts for that lens. Th...

So I was in the market for a wide angle. I thought I would give this one a go to see if I could accomplish my goals and save some major buckaroos. Sad to say this lens fulfills the adage, you get what you pay for. It's nice and wide but doesn't have the crispness that I was looking for and had to go...

Be careful! This lens MIGHT not work with the Sony a77 (and a65)! Yesterday this lens arrived, I attached it to my a77, and found that the autofocus did NOT work! After searching around the Web, I found a page on the Sigma Web site that said there are TWO recent versions of this lens: an older versi...

I bought Sigma lenses for my Pentax system, I cannot afford to buy Pentax lenses especially the DA version because it is very expensive especially for a college student like me. I wish Sigma Corporation will continue to support Pentax System, unfortunately they are already cutting them due to lack o...

I use a Canon Rebel T3i and this is the first non-Canon lens I have purchased. I did two months of research before buying this lens. I am a photo enthusiast who likes taking great pictures for personal and professional use (I'm a hospice chaplain and use my camera for facility functions and church e...
